PEA OR BEAN SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 631 ,946, dated August29, 1899. Application filed November so, 1898 Serial to. 697,872. (Nomodel.)

To all whom it may concern.- I

Be it known that 1, JOHN H. BAK R,acitizen of the United States,residing at Spivey, in the county of Clay and State of Tennessee,- haveinvented a new and useful Pea or Bean Separator, of which the followingis a' specification.

This invention relates to machines for threshing and hulling peas,beans, and the like; and it has for its object to provide a simple andefficient machineof this charac ter having improved means for thoroughlythreshing and cleaning the product without breaking or cracking thesame.

T 0 this end the invention contemplates an improved construction ofthreshing 1nechan-. ism for hulling peas, beans, and the like inconnection with means for eifecting a com: plete separation of the hullsand trash from the product before delivering the same from the machine.

W'ith these and other objects in View, whichwill readily appearas thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

While the essential and characteristic fea-. tures of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of a separating or threshing machineconstructed in accordance with the present invention. Fig. 2 is averticallongitudinal sectional view of the machine. Fig. 3 is a verticaltransverse sectional view on the line 3 3 of Fig. 2. Fig. 4. is a detailin perspective of the threshing or hulling wheel. Fig. 5 is a detailsectional view of a portion of the threshing or hulling wheel.

Referring to the accompanying drawings, the numeral 1 designates thecasing of the machine, built within a suitable exterior framework 2,having short pendent legs 3, providing a support for the machine, andsaid casing 1 essentially consists of opposite inclosingsides and aslide-top 4, mounted in suitable ways in the top of the casing andaffording convenient meansforgaining access to the interior parts withinthe casing for the purpose of cleaning or adjusting the same.

The machine casing 1 supports on top thereof at one enda segmentalconcave boxing 5, preferably bolted or otherwise firmly secured in placebetween upright post extensions 6 of the exterior framework 2 of thecasing. The concave boxing 5 is provided with a curved shell 7, having abottom discharge-opening 8 communicating directly with the interior ofthe machine-casing near one end thereof, and said curved shell 7 of theboxing is confined between the opposite straight side walls 9 thereof,and said straight side walls 9 of the concave boxing 5 have projectedinwardly within the boxing a plurality of closely-arranged stationaryteeth 10. The teeth 10, which projectinwardly from the opposite sidewalls 9 of the concave boxing, have their outer ends bolted, as at 11,in said side walls, so that the same can be removed and replaced at anytime required.

The space above the concave boxing 5 is inclosed by a detachable hopper12, consisting of a flaring frame resting directly on top of the boxing5 and provided at one end with a pairof hooks 13, having a detachablehinge engagement with the eyes 14, fitted to one end of the concaveboxing 5, this connection between the boxing and the hopper permittingthe latter to be swung on the hooks 13 as a hinge, so as to expose thethreshing mechanism whenever necessary. At the end opposite thehinge-hooks 13 the hopper 12 is provided with a pivotal L-shaped latch15, adapted to be turned in and out of engagement with a pin or stud 16,projecting from one end of the concave boxing. The latch 15 serves tolock the hopper on the concave boxing while at the same time permittingit to be raised whenever required, and at this point it will be observedthat the hopper 12 not only serves to receive the supply of peas orbeans to be thresh ed, but at the same time forms a part of the ho usingfor the vertically-disposed threshing or hulling wheel 17, mounted toturn within the concave boxing. I Y

The threshing or hulling wheel 17 rotates between the stationary teeth10, projected from the opposite Walls 9 of the boxing 5, and said wheelessentially comprises a pair of duplicate circular disks 18, arrangedback to back and having peripheral abutting flanges 19 receiving thesecuring-bolts 20 for holding the two disks together to form thecomplete body of the wheel 17. The duplicate registering disks 18 arepreferably made of sheetiron of a suitable thickness, and each of saiddisks carries a plurality of laterally-extending threshing spikes orteeth 22, which work through the spaces between the stationary teeth 10of the concave boxing. The threshing spikes or teeth 22, which areprojected laterally from each of the wheel-disks 18, are provided withinner bolt ends 23, which pass through openings formed in the disk andreceive thereon the fastening-nuts 24, arranged at the inner side of thedisk, and are therefore housed entirely within the wheel. After thethreshing spikes or teeth have been inserted in each wheel-disk from theoutside thereof and bolted thereto in the manner explained woodenfilling-blocks 25 are placed within the inner sides of the wheel-disksover the nuts 24, so that when the two disks are bolted together aloosening or falling out of the spikes or teeth is positively prevented,while at the same time the separable wheel may be readily opened upwhenever it is necessary to remove and replace a broken spike or tooth.By reason of the construction of threshing or hulling wheel described itwill be observed that the spikes or teeth project horizontally andlaterally from opposite sides thereof, and an essential feature of theinvention is the relative arrangement of these teeth at each side of thewheel.

As shown in Fig. 4 of the drawings, the threshing spikes or teethprojecting from each disk or side of the wheel 17 are grouped into aseries of radial rows 26, all of which converge toward the axis of thewheel and into a circular peripheral row 27. The circular peripheralrows 27 of the threshing spikes or teeth at each side of the wheel 17are arranged near the peripheral edge of the wheel and exterior to theradial rows 26, so as to completely encircle the latter, and the purposeof the circular peripheral rows 27 of the threshing spikes or teeth isto retain or hold the peas or beans within the working area of the wheeluntil the hulls are completely broken and threshed therefrom.

The threshing or hulling wheel 17 is mounted on a transverse wheel-shaft28, journaled in suitable bearings 29 at opposite sides of the boxing 5and carrying upon one end the pinion 30, meshing with a spur-gear 31,mounted on one end of the transverse drive-shaft 32, mountedtransversely of the machineframe and carrying on the end opposite thespur-gear 31 a belt-Wheel 33, which communicates motion to a drive-belt34, while motion is communicated to the shaft 32 by means of a crank 35or by power through the medimounted on the shaft 32. The belt 34 passesover a belt-pulley 37, mounted on one end of the pitman 49.

the fan-shaft 38, journaled transverselyof the machine-casing at one endthereof and carrying within the casing a blast-fan 39. The Saidblast-fan 39 receives its supply of air from the inlet-eyes 40, formedin opposite sides of the machine -casing 1, and works within the fancasing or rim 41, built within one end of the machine-casing and servingto deflect the blast forward through the machinecasing over the inclinedchute-board 42, extending lengthwise thereof from end to end. Theinclined chute-board 42 extends below the fan casing or rim 41 and isprovided at its lower end with a contracted chute portion 43 for thedelivery of the hulls and cleaned peas or beans into a suitablereceptacle therefor. The upper or higher end of the inclined chute-board42, which is arranged beyond the fan 39, is disposed below ashaking-riddle 44. The riddle 44 is slidably supported at an inclinationor in suitable supports 45, fitted at opposite inner sides of themachine-casing,

. and said riddle is suspended at one end from the hanger-links 46,loosely connected with a transverse supporting-rod 47, fitted in themachine-casing, and the end of the riddle which is suspended from thehanger-links 46 has connected thereto the angled end 48 of The angledend of the pitman 49 works through a slot 50 in one side of themachine-casing, and the other end of said pitman connects with a crank51 on one end of the fan-shaft 38.

The shaking-riddle 44 is arranged directly beneath the bottomdischarge-opening 8 of the concave boxing 5, so that the threshed peasor beans, with their crushed and broken hulls, fall directly onto theriddle, and the blast of air from the fan will carry out the hulls andother trash through one end of the machine-casing, while the peas orbeans separated therefrom by the riddle fall onto the chute-board 42 androll down the same into the receptacle provided therefor. In thisoperation of the machine it will be observed that the drive-shaft 31simultaneously communicates motion to the threshing or hulling wheel andalso to the fan, while the latter through 1 the medium of theconnections described imparts an oscillating reciprocatory motion to theriddle. I

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described machine will be readily apparentto those skilled in the art without further description, and it will beunderstood that changes. in the form, proportion, and the minor detailsof construction may be resorted to without departing from the principleor sacrificing any of the advantages of this invention.

Having thus described the inventi0n,what is claimed as new, and desiredto be secured by Letters Patent, is um of a belt applied to abelt-pulley 36, also 1. In a separator-machine, thecombination of acasing havlng a concave boxing provided with stationary teeth projectedinwardly from IIO opposite sides thereof, a hopper detachablysurmounting said boxing; a vertically-arranged threshing or hullingwheel Working Within the boxing and having duplicate circular disksarranged back to backand detachably bolted together, aplurality ofspikes or teeth detachably bolted to each of said disks, an inclinedchute-board forming the bottom of said casing, a shaking-riddle looselysuspended within the casing beneath the concave boxing, a blast-fanmounted for rotation within the casing beyond the riddle, and aconnection between the fan-shaft and said riddle.

2. In a separator-machine, the combination with the concave havingstationary teeth at opposite sides thereof, of a threshing or hull ingwheel consisting of a pair of duplicate circular disks arranged back toback and de- .tachably bolted together, and a plurality of spikes orteeth detachably bolted to each of said disks, substantially as setforth.

8. In a separator-machine, the combination with the concave, of athreshing or hulling wheel consisting of a pair of duplicate circulardisks arranged back to back and provided with peripheral abuttingflanges detachably bolted together,a plurality of threshing spikes orteeth having their inner ends bolted within each of said disks, andfilling-blocks fitted within said disks, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
